It is unclear whether Selis, a resident of the apartment complex, knew the victims. One witness told NBC San Diego that the tenant who was celebrating his birthday invited Selis to join the party.That’s when Selis raised his shirt, took out a gun and shot him in the stomach. He is expected to survive.

One witness told the station that Selis smirked during the shooting. Another said he was holding a beer in one hand and a gun in the other.

Kaela Wong, 20, who was sitting in a nearby hot tub, told the San Diego Union-Tribune that Selis threatened some women who were trying to help a victim.“You can either leave or you can stay here and die,” Wong said she heard Selis say.

The shooting ended shortly after officers arrived on the scene, according to Zimmerman. Twenty officers and a police helicopter had been sent. Selis was observed apparently reloading his weapon. Officers fired when he then pointed it at them.

Amit Godbole heard the gunfire from his apartment, he told the Union-Tribune.

“It was like a war zone or something,” Godbole said. “There would be three or four shots, a pause and then more shots. I was trying to count them. I counted 30 or 40.”

Court records show he filed for bankruptcy in October 2015, claiming debts of $108,028 and only $14,100 in assets. At the time, he listed a 12-year-old daughter, a 16-year-old son and a 19-year-old stepson on the forms.
